BLOWER MOTOR
DESCRIPTION
Vehicles equipped with 4 passenger seating and
automatic temperature control (ATC) heating-A/C
system, use a 12-volt, direct current (DC) rear blower
motor. The rear blower motor has an integral wire
harness and two squirrel cage-type blower wheels
that are secured to the blower motor shaft (Fig. 1).
The blower motor and wheels are contained within
the two halves of the rear blower motor housing,
which is located under the front center floor console
cover.
OPERATION
The rear blower motor and wheels are used to con-
trol the velocity of air moving through the center
floor console ducts by spinning the blower wheels
within the housing at the selected or programmed
speed (depending on application).
The rear blower motor will operate whenever the
ignition switch is in the On position and the power
for the A/C-heater control of the automatic tempera-
ture control (ATC) heating-A/C system is turned on.
When the ATC A/C-heater control display reads
REAR AUTO or when the rear blower motor is off,
the switch located in the center console between the
second row seats is not functional. When the A/C-
heater control display reads REAR, only the rear
seat occupants control the rear blower motor speed
from the rear switch. When in the Rear mode, the
rear occupants can set the rear switch to any blower
motor speed including OFF or AUTO. While in the
Auto position, the rear blower motor speed will be
automatically controlled.
The rear blower motor speed is controlled by an
electronic blower motor power module, which uses a
pulse width modulated input from the ATC A/C-
heater control and feedback signal from the rear
blower motor to regulate the blower motor ground
path. The rear blower motor receives battery current
whenever the rear blower motor relay is energized.
For diagnosis and testing of the rear blower motor,
refer to 24 - HEATING & AIR CONDITIONING/DIS-
TRIBUTION - FRONT/BLOWER MOTOR - DIAG-
NOSIS AND TESTING.
The rear blower motor and blower motor wheels
are factory balanced and cannot be adjusted or
repaired. If faulty or damaged, the rear blower motor
and blower wheels must be replaced as an assembly.
